First of all to the Forum.
Second, very sorry to hear you are having issues with your BG.380, I carry one on a daily basis and have had no issues. I only have about 3 to 4 hundred rounds through it, but it has been flawless. The first thing I did was put a drop of blue Loctite on the laser mounting screw, because I read that some people were having trouble with the screw backing out. If you continue to have issues I would contact S&W and let them know.
